27 Claims.

This invention relates to impressed covers and to the method of production.

More particularly, the invention relates to covers for publications such as magazines and to covers for other suitable articles, the cover comprising front and back cover portions of multiple ply, the exposed faces of which, that is, the obverse and reverse faces of the respective 'cover portions, are impressed with printed and/or other matter. Preferred forms of the invention include multiple ply also at the hinge, or thebackbone portion,of the cover, such portion being better known in the bookbinding art as the back portion of the cover.

Pursuant to the method of my invention, the paper or other stock in blank, and preferably in web form, is impressed upon one face only with the printed and/or other matter. The stock is then folded in such manner that the impressed faces are outermost in the final product. The resulting superimposed plies maybe secured to one another, preferably by bonding with adhesive, to form multiple-ply cover portions-for the cover. My invention is of especial utility in enabling the desired total printing and other impressions, particularly of multi-color values, to be carried out upon one face only of the stock, and accordingly at a single operation, also affording the output of highly satisfactory products by use of relatively thin stock, 1. e. of lesser point. My

- invention is also advantageous in that the stock material may in itself comprise multiple plies including a ply of cheaper grade as the body, and a relatively thin ply of finish grade, the printing or other impressions being applied upon the finish face of the multiple ply stock. or, an inferior grade stock may be provided on one face with a high grade finish for the reception of the impression.

A characteristic of covers, pursuant to my invention, resides in the fact that the terminal edges of the terminal ends of the cover portions are rounded and smooth. Such terminal'edges are uncut.

Further features and objects of the invention will be more fully understood from the following detail description and the accompanying drawing, in which Fig. 1 is a top plan view, largely diagrammatic, showing a procedure of carrying out my invention in its web phase, followed by stages of folding and of bonding the folded portions to form the desired cover.

Fig. 2 is a side elevation of Fig. 1.

Fig. 3 is an end edge view of a type of cover resulting from the procedure indicated in Fig, 2; this view also applies to a cover similarly formed, pursuant to my invention, from a blank in lieu of a web.

Fig. 4 is an end elevation of a magazine, including its leaves, having a cover of the type shown in Figure 3.

Fig. 5 is a detail end elevation of a magazine, including its leaves, having another embodiment of cover pursuant to my invention, and illustrated onan enlarged scale.

Fig. 6 is an end elevation of a magazine, including its leaves, having another embodiment of cover, pursuant to my invention.

Fig. 7 is a detail perspective view of another embodiment of my invention, illustrating the principle of one or more fiy leaves, printed or nonprinted, as preferred.

The procedure indicated diagrammatically in Figs. 1 and 2, illustrates the carrying out of my invention in its web phase, a form of my invention which possesses especial economies in the commercial utilization of my invention, as is apparent. However, as hereinabove and hereinbelow set out, my invention is not limited to such web phase of its utilization, and is applicable, inter alia, to the phase of individual blanks treated in a manner corresponding with the web phase of my invention.

Referring to Figs. 1 and 2, It) indicates a web of paper or other suitable stock, which has been printed as is indicated at Ma. It will be understood that each and all of the spaces Illa are likewise printed or otherwise impressed, the repetition of the consecutively repeated printed or other impressed matter being omitted for convenience. The lines Illa" indicate the margins between the repeated printed areas.

H represents an adhesive applying roller and I2 its complementary pressure roller, adhesive being applied to the effective face of the roller II by any suitable means, such as an applying roll l3 contacting in turn with the effective face of the roller H and the face of the feed roller M, which last named may be partly immersed in a bath l5 of the adhesive contained in the 'reservoir I6, or the equivalent of the above. By such or other approved procedure, adhesive is applied to the unprinted face I017, see Fig. 2, of. the web I0. 7

Subsequent to the stage of application of adhesive, the laterally opposite margins of the web, indicated at I0c, are folded inwardly against the mid-portion of the web so that unimpressed faces 9f the web are contiguous, the folding and the bonding of the juxtaposed adhesive applied faces being completed by one or more sets of complemental pressure rolls H.

The thus or otherwise folded and bonded web portions are then severed by suitable severing means at the marginal lines Illa", as by a set of complemental severing rolls Ila, thus yielding individual covers. A severing blade is indicated at I'Ib.

Correspondingly, in carrying out the blank phase of the invention, individual blanks of the full width, are appropriately printed or otherwise impressed upon one face, adhesive applied to the under, i. e., unimpressed face and laterally opposite portions respectively folded to form the desired cover.

One type of cover, pursuant to my invention, is indicated in Fig. 3, the desired printing or other impressions appearing on one or both faces Illa, as optionally preferred, of the front and back cover portions. In Fig. 3 there is indicated at 18 a reduced thickness of the cover, appropriately and herein termed the hinge or backbone of such cover. The backbone portion of the type shown in Fig. 3 is effected by spacing the terminations, i. e. edges, see We, llle, from one another; The backbone thus comprises one ply of the material whereas each cover portion comprises two plies. A magazine having the type of cover shown in- Fig. 3, is indicated in Fig. 4, its leaves l9, usually comprised of one or more signatures, stapled, sewed or otherwise bound to one another, being suitably secured at their aligned edges l9a to the backbone l8. The securement is preferably of permanent form for the life of the magazine.

As is indicated in Fig. 1 by the manner of folding of the edges Hle, namely in butt to butt relationship, each individual cover results in the type indicated in Fig. 5, namely, having its backbone portion l8 of double, i. e., the same number of plies as the respective folded cover portions, the leaves IQ of the book, of one or more signatures, or equivalent, being suitably permanently secured, see l9a, to such backbone portion l8 of the cover.

In Fig. 6 is shown another type of cover, name- 1y. providing for overlapping at the backbone portion of the cover, thus efiecting an increased number of plies at the backbone portion l8" of the resulting cover as compared with the number of plies of each cover. Such form of cover is particularly applicable for magazines and the like, the leaves 19 of which are secured by staple, see 20, or other mechanical form of attachment to the cover, the increased number of plies at the backbone portion enhancing such mechanical attachment.

Recurring to the type of cover shown in Figs. 3 and 4, the widths of the inner plies of the cover portions are, respectively, less than one-fourth of the total width of the web or the blank. In the type of cover shown in Fig. 5, the widths of the inner plies of the cover portion, are exactly onefourth of the total width of the web or the blank. In the type of cover shown in Fig. 6, the widths of the inner plies of the cover portions are, respectively, greater, to a desired extent, than one fourth of the total width of the web or the blank.

-It will be observed that in the above embodiments ofmy invention, the eventual terminal edges,see 2|, of the terminal ends of the cover portions by reason of the stated folding operations, are each rounded and smooth, thus avoiding the so-called raw edges inevitably ensuing upon cutting or other severing operation.

It is apparent that each cover portion may be I formed of a number of plies in excess of two by suitable folding, the printing being confined to the portions of the blank or web which eventually become the inner and outer faces, that is, the reverse and obverse faces, of the respective cover portions.

' My invention may also afford an integrally connected fly leaf for each or both of the respecprinted, if desired.

Economy in cost of material and also increased tensile, shearing and puncture strengths, as well as enhanced qualityof product are attained, by the laminated structure of the front and the rear cover portions, in which, incidentally, thinner than usual stock may be utilized. Individual plies are serially and integrally connected. The intervening layer of adhesive may be selected and applied to enhance the degree of flexibility or rigidity of the resulting laminated structure.

It should be noted that the present invention refers to covers which are adapted to positively bind suitable inserts such as publications, blank sheets, book-matches and articles having generally similar characteristics. For this purpose, each cover pursuant to this invention is provided with a back portion which integrally connects multiple-ply cover portions and provides hinge action for the cover portions relative to each other,and, pursuant to the method of this invention, the blank after being formed, is folded to produce the desired line ofv hinge in providing the resulting cover with the required back portion and with integrally related cover portions for the reception and the securement in book formation, of a suitable insert.

It is advantageous that the back portion of the cover be formed at and along that portion of the blank or web at which the original lateral edges thereof are located after the first folding and securing operations. That is to say, that intermediate location in the blank or web at which those edges of the blank or'web which were the original lateral edges thereof, just meet or are spaced apart, or overlap, pursuant to the preferred type of folding operation afore-described in detail, is ideally adapted to become the back portion of the cover for the reception and positive'securement of the insert.
